Typhoon Pabuk or Chedeng was a weak typhoon that formed during the day of August 5. The system made landfall on Taiwan on August 7, and on August 9 Pabuk passed to the south of Hong Kong. The name "Pabuk" was submitted by Laos, and refers to a large freshwater fish in the Mekong River. [ [http://www.weather.gov.hk/informtc/sound/tc_pronunciatione.htm#Lao] ]

torm History

storm path|Pabuk 2007 track.pngA tropical disturbance developed southeast of Chuuk early on July 31. The system moved west-northwestward over the next several days with little change in organization. On August 4, however, organized convection quickly began to redevelop, and the Japan Meteorological Agency began monitoring it as a tropical depression. The system continued to strengthen, and the Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert on the system early the next day, noting that its environment was "strongly favorable for development". [ [http://www.webcitation.org/5QrV9UEcZ WebCite query result ] ] The Japan Meteorological Agency designated the system Tropical Storm Pabuk shortly after. [ [http://www.webcitation.org/5QrUisG7f WebCite query result ] ] The JTWC designated the system Tropical Storm 07W at about the same time, and on August 5 PAGASA named the system Chedeng. As Pabuk continued to move to the northwest, it gained some organisation as it slowly developed outflow. [ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2007080603-WDPN.PGTW] It was upgraded by the JMA to a severe tropical storm on August 6. Moving westwards towards Taiwan, an area of convection south of Pabuk separated and formed its own low-level circulation. Pabuk's upper-level outflow inhibited this new area of convection. Strengthening slightly, Pabuk was upgraded to a typhoon on the morning of August 7. The JTWC downgraded Pabuk to a tropical storm later that day, with the JMA downgrading Pabuk shortly before landfall. It made landfall in southern Taiwan around 1630 UTC according to Taiwan radar and crossed the southern tip of the Hengchun Peninsula in Pingtung County. The JTWC re-upgraded Pabuk to a typhoon at its next advisory, however, citing a small eye at landfall, [ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2007080721-WTPN.PGTW] before downgrading it to a tropical storm again three hours later.

After passing over Taiwan, Pabuk took aim at Hong Kong. [ [http://www.webcitation.org/5Qw3hcrHE WebCite query result ] ] On August 9 as the system passed to the south of Hong Kong JMA downgraded the storm to a tropical depression later that day and issued its final public advisory, with the JTWC following suit shortly after. The tropical depression then turned back to the east-northeast on August 10 [ftp://ftp.met.fsu.edu/pub/weather/tropical/Tokyo/2007081000.RJTD] , forcing the HKO to re-issue signal 3. The HKO also warned that winds were expected to strengthen further locally, and that the Hong Kong Education Bureau had suspended all classes for the day. [ [http://www.webcitation.org/5Qyz1SfjJ WebCite query result ] ] The HKO upgraded Pabuk to a tropical storm [ [http://www.info.gov.hk/gia/wr/200708/10/P200708100166.htm PRESS WEATHER NO. 103 - TROPICAL CYCLONE BULLETIN (SIGNAL NO. 3)] ] Later that day Pabuk moved closer to the territory.

The Hong Kong Observatory (Or HKO) and Macau's Meteorological and Geophysical Bureau both hoisted strong wind signal 3 on August 9 as the system passed to the south of Hong Kong, they were canceled later. On August 10 the Signals were re-issued as the Cyclone went back on itself. The HKO also warned that winds were expected to strengthen further locally, and that the Hong Kong Education Bureau had suspended all classes for the day.
